GKN driveshaft replacements? Ref. Zappe's XJ Builder's Guide

Okay, so the stick-in-the can finally blew out on me--ripped out of the output shaft/flange/'can'. I've read in Zappe's XJ Builder's Guide that it can be replaced with a "Spicer driveshaft yoke for the transfer case and a stock Spicer drive shaft that is the correct length."

I have an '84 with a good 3.5" of lift (I knew it was only a matter of time that the GKN went out on me). NP-207 t-case. Torqueflight 304 (3-speed auto).

My question...does anyone know which driveshaft and yoke would fit?I don't have enough spare change to get a custom shaft, and even if I did I dont think I'd throw something that expensive under my 84 I know that the ds length depends on the engine and t-case used...I've searched and searched and know that I have the red-headed step-child of the Cherokee family--but any help would be great, not having 4x4 defeats the purpose of my Heep.

TIA Ed

Lots of people have had this problem

quick question if anybody knows, what 231's had the 26 spline front output, was it all of them or certain years?
